Sequencing Batch Reactor (SBR) technology is a suspended growth biological treatment process whereby the microorganisms are aerated, settled, and the effluent decanted in the same reactor.

In SBR technology, wastewater undergoes cycles of aeration, mix, settle and decant. The process degrades soluble organic material and removes nitrogen via the nitrification and denitrification process. Excess bio solids are removed by a waste activated sludge pump.

AeroSBR uses Aerofloat’s unique, patent-pending aeration lance design and its unique Air Locked Syphon (AeroALS) decanter to ensure a maintenance friendly plant.

Aerofloat has extensive experience in the biological treatment of wastewater and can offer its AeroSBR patented design, or manufacture conventional SBRs if larger, more traditional systems are required.

Sequence Steps

The AeroSBR comprises cycles of aerate, mix, settle and decant. This ensures optimal removal of nitrogen by the nitrification/denitrification process.

Diffuser Cleaning Without Downtime

The unique design of the AeroSBR aeration lances allows them to be removed for cleaning while the process is still in operation. This eliminates the need to drain the tank or shut down the system.

Clarification in Same Reactor

Aerating, settling and decanting in the same reactor overcomes the need for a separate clarifier, and in the case of the MBRs, also prevents frequent membrane cleaning or replacement.

Air Locked Syphon (ALS) Decanter

Unlike conventional SBRs with lowering decanting weirs, the AeroALS decanter can be installed in covered tanks enabling the AeroSBR to be sealed and vented, preventing any unpleasant odours from escaping.
